How do Fuse Box and Relay Boxes protect circuits from excessive current flow on 2015 Audi A3?

The operation of fuses is based on the fact that when faults occur, the circuit is broken because of high current flow. The driver side fusebox contains the main fuses, and can be accessed by unclipping the cover. Install appropriate replacement fuses. There are other fuses and relays in the engine compartment. Relays can carry heavy currents, and can be tested when faulty.
